条件状语从句详解

条件状语从句是一种状语从句,用于表示某个条件下的结果或假设,通常由连词引导。其结构通常由“条件”(从句)和“结果”(主句)两部分组成。在初中高中阶段,常见的引导条件状语从句的连词有if(如果)、unless(除非,如果不)、as long as(只要)、on condition that(条件是)、provided(that)(假如)、supposing(that)(假设) 、in case(万一)等。

需要特别注意的是,在含有条件状语从句的复合句中,要遵循“主将从现”原则,即主句用一般将来时态,祈使句或情态动词,从句要用一般现在时态 。不过,if引导的条件句还有真实条件句和非真实条件句(虚拟语气)两种情况,非真实条件句表示与事实相反,动词形式会有所不同。
